用一体式胶粘剂在牙根表面涂膜是预防牙根表面龋病的一种有效方法。本研究的目的是研究两种一体化涂层材料对牙刷磨损的耐磨性；屏蔽力（SF）和混合涂层（HC）。用其中一种涂层材料覆盖牛牙本质表面；SF还是HC。在水中储存24小时后，测试表面在水中或牙膏浆中进行高达50,000次的牙刷磨损试验。利用扫描电镜测量了涂层材料的剩余厚度。牙膏浆明显增加了牙刷对涂层材料的磨损率。虽然SF和HC在牙刷磨损下的磨损速度相似，但SF的涂层更厚，保护牙本质的时间更长，可达5万次。
Thin-film coating of root dentin surface by all-in-one adhesives has been shown to be an effective option to prevent root surface caries. The purpose of this study was to investigate the wear resistance against toothbrush abrasion of two all-in-one coating materials; Shield Force (SF) and Hybrid Coat (HC). Bovine dentin surfaces were covered with one of the coating materials; SF or HC. After storage in water for 24 h, the testing surface was subjected to the toothbrush abrasion test up to 50,000 cycles either in water or toothpaste slurry. The remaining thickness of the coating material was measured using SEM. Toothpaste slurry significantly increased rate of tooth brush abrasion of the coating materials. While SF and HC wore at a similar pace under toothbrush abrasion, SF had a thicker coat and could protect dentin longer, up to 50,000 cycles.
